Image Processing System, Method, and Non-Transitory Computer Readable Medium

1. An image processing system comprising: a processor configured to act as: a reception unit that receives an image forming instruction from a user; a retaining unit that retains the image forming instruction in association with the user; an acceptance unit that accepts an execution instruction from the user; an authentication unit that performs authentication of the user; and an image forming unit that executes the image forming instruction retained by the retaining unit in association with the authenticated user when a predetermined holding time elapses, the holding time being counted from a time point at which the authentication completes the authentication, the image forming unit executing the image forming instruction without accepting the execution instruction by the acceptance unit in a case where the authentication unit completes the authentication and cancellation of execution by the user is not present within the holding time.

2. The image processing system according to claim 1 , wherein the cancellation of execution by the user is at least one of an instruction from a mobile terminal of the user, a predetermined gesture of the user, and a predetermined utterance of the user.

3. The image processing system according to claim 1 , further comprising the processor configured to act as a notification unit that notifies the user of the holding time.

4. The image processing system according to claim 3 , wherein the processor acting as the notification unit notifies for which user the holding time is given in a case where the retaining unit retains image forming instructions of a plurality of users.

5. The image processing system according to claim 1 , further comprising the processor configured to act as a second acceptance unit that remotely accepts the cancellation of execution by the user.

6. An image processing method comprising: receiving, with a processor, an image forming instruction from a user; retaining, by the processor, the image forming instruction in association with the user; accepting, by the processor, an execution instruction from the user; authenticating, by the processor, the user; and automatically executing, by the processor, the image forming instruction retained in association with the authenticated user when a predetermined holding time elapses, the holding time being counted from a time point at which the authentication completes the authentication, and without accepting the execution instruction in a case where the authenticating is completed and cancellation of execution by the user is not present within the holding time.

7. A non-transitory computer readable medium storing a program that causes a computer to execute: receiving, with a processor, an image forming instruction from a user; retaining, by the processor, the image forming instruction in association with the user; accepting an execution instruction from the user; authenticating, by the processor, the user; and executing, by the processor, the image forming instruction retained in association with the authenticated user automatically when a predetermined holding time elapses, the holding time being counted from a time point at which the authentication completes the authentication, and without accepting the execution instruction in a case where the authenticating is completed and cancellation of execution by the user is not present within the holding time.
